1 Koruna Iron trial strike

Slovakia's wartime switch to iron coinage was driven by German pressure to conserve copper and nickel for military production — a policy applied across occupied and client states from 1940 onward. The 1 Koruna iron trial strikes from 1942 were part of the technical evaluation process before full production commitment, and most were either destroyed or retained by the mint. Very few left official channels.

The Slovak State mint in Kremnica handled these tests. Kremnica's records from the occupation period are incomplete, and precise trial strike populations remain unconfirmed.
